摘要

随着深海资源的勘探、开发和研究,迫切需要长期、连续的深海海底边界层观测数据。传统的基于科考船的深海海底调查和取样方法存在观测数据在空间和时间尺度上的不连续性。基于海底观测网络的海底原位观测方法存在移动性差、运维成本高等问题,制约了对深海海底动态变化过程的深入了解。为解决上述问题,设计了基于嵌入式系统和信号处理技术的开放式模块化数据采集控制系统。针对海底或海底边界层附近的物理、化学、地质和生态系统特征,匹配各种功能传感器和仪器设备,形成独立的水下综合测量或实验装置,最终实现对海底的原位多参数和长时间序列观测。通过实验室实验完成了系统数据采集和控制测试,验证了系统设计的可行性。该研究对海底边界层资源勘探开发和促进深海科学研究具有重要的理论和技术参考意义。

Design of a multiparameter data acquisition and control system for in situ seabed observation base stations

Design of a multiparameter data acquisition and control system for in situ seabed observation base stations

With the exploration, development, and research of deep-sea resources, there is an urgent need for long-term and continuous observation data of the deep-sea seabed boundary layer. The traditional method of deep-sea seabed survey and sampling based on scientific research vessels has the discontinuity of observation data in space and time scales. There are some problems in the seabed in situ observation method based on the seabed observation network for low mobility and high operation and maintenance costs, restricting the in-depth understanding of the dynamic change process of the deep-sea floor. To solve the above problems, an open and modular data acquisition control system was designed based on an embedded system and signal processing technology. In terms of the physical, chemical, geological, and ecosystem characteristics of the seafloor or near the seafloor boundary layer, various functional sensors and instrumentation were matched to form an independent underwater integrated measurement or experimental device, eventually realizing in situ multiparameter and long-time series observations of the seafloor. The system data acquisition and control test were completed through laboratory experiments, which verified the feasibility of the system design. The research showed important theoretical and technical reference significance for the exploration and development of resources in the submarine boundary layer and the promotion of deep-sea scientific research.
